What is BST in AWST?
Australian Western Standard Time is 7 hours ahead
British Time is on UTC+1:00 and Australian Western Standard Time is on UTC+8:00 right now. British Time is on daylight saving, so its clocks read BST. The gap changes during the year — see below.

When the difference changes
British Time and Australian Western Standard Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:
- Now – October 25, 2026Australian Western Standard Time is 7 hours ahead
- October 25, 2026 – March 28, 2027Australian Western Standard Time is 8 hours ahead
- March 28, 2027 – onwardsAustralian Western Standard Time is 7 hours ahead
Periods shorter than a day are not listed: both zones change at 2am in their own local time, so there are a few hours on each transition date when the gap is briefly something else.
Daylight saving
British Time
Clocks go back one hour at 2am local time, becoming GMT.
Australian Western Standard Time
Australian Western Standard Time stays on AWST all year, so its offset from UTC never moves.

A note on BST: it can also mean Bangladesh Standard Time (UTC+6). This page means British Summer Time.
British Time (BST) is used in the whole United Kingdom. In winter the UK is on GMT; from late March to late October it is on BST, an hour ahead.
Australian Western Standard Time (AWST) is used in Western Australia, which does not observe daylight saving
